La #TeamPat #PSTN #collections #muséums sera particulièrement intéressée par cette intervention :
#PSTN Webinaire public le 12 juin.
Mise en place théorique d’une chaîne opératoire de manipulation et de conditionnement pour des #collections qui posent une problématique de toxicité :
- l’amiante,
- l’arsenic,
- les formaldéhydes,
- le mercure,
- le plomb
- et la radioactivité.

Vous avez encore une semaine pour soumettre une idée de contribution à cet appel : "Philosopher au musée" !
(j'espère qu'il y a aura des papiers #PSTN !)

Appel à contributions – Philosopher au musée - Implications philosophiques

Appel à contributions Philosopher au musée Revue Implications philosophiques Dossier coordonné par Guillaume Lurson, agrégé de philosophie et docteur. Élève conservateur du patrimoine, spécialité musées. Descriptif du projet : Paul Valéry écrivait, dans Le Problème des musées : « Je n’aime pas trop les musées. Il y en a beaucoup d’admirables, il n’en est point de délicieux. Les idées de classement, de conservation et d’utilité publique, qui sont justes et claires, ont peu de rapport avec les délices. ». Le rapport que les philosophes entretiennent avec les musées semble d’abord marqué par la méfiance, voire par une certaine défiance (Valéry, 1923 ; Dewey, 2010 ; […]

Now the other two are ported - all the #analogue #trunks are ceased and all traffic to and from the #PSTN from this #PBX is now #VOIP (using #PJSIP trunks on #FreePBX )

I disconnected all the analogue lines as #Openreach leave battery on them, that way they show as RED alarm on #Asterisk and won't be selected for any calls (worst case is they return a busy trunk status and the route will go to the next trunk, but I've taken away all the analogue circuits from every PSTN route)

#Telecoms #Telephony

One (1) #telephone number successfully ported to #VOIP, one more left to go (there's 2 pairs for main and aux line, provisioned on same number but those will go to 3 channel #SIP trunk)

For some reason #Openreach have left battery on the pair (I would have thought they would want to recover capacity on the line card and it would just go dis, as there are still going to be a handful of customers remaining on #PSTN circuits.

I thought a lot of "analogue" trunks these days were literally just a SIP ATA connected to the copper pair at the Telephone Exchange (or from a street cabinet) but it looks like Openreach really are getting the last out of the old #SystemX kit!

There is no dialtone or even NU tone, just some noise..

#Telecoms #Telephony

Just spent half day reconfiguring #SIP trunks on #FreePBX and #Asterisk (using chan_pjsip) as one of our providers silently yoinked #IAX2 support - #VOIP is as cursed if not more so than #PSTN / #ISDN circuits, except you don't have to crawl around as much in corners and roofspaces amongst spiders, mouse-like rodents and possibly snakes (if you have them in your country), and there's less chance of ending up on the wrong side of 100-120 volts (either AC or DC, depending on whether its ringing voltage or the strong DC voltage that British Telecom and others used to send down certain ISDN lines in 90s/00s)

UK regulatory body OFCOM has fined Virgin Media £23.8 million for putting vulnerable customers at risk of harm during the switch from analogue to digital telephony.

OFCOM press release - https://www.ofcom.org.uk/phones-and-broadband/vulnerable-customers/ofcom-fines-virgin-media-23.8-million-for-putting-vulnerable-customers-at-risk-of-harm

Nice (but admittedly very surprising) to see a UK regulator handing out a hefty fine for cutting off access to lifesaving telecare alarms during the switchover.

Vulnerable people were always going to be at risk from the switch from good old analogue phone lines (PSTN) to digital lines (VOIP).

The switchover was not mandated by government - it is an industry led programme. Consequently there will be gaps, errors and omissions because corporate people stuck in offices staring at spreadsheets don't always have the full picture and thinking of older and vulnerable customers at the forefront of their way of working.

IIRC, UK government didn't do much to ensure best practice, proper consultation and good communications to customers until people started to complain to their MPs. Then words were had, guidance issued and deadlines for the final analogue switch off extended.

I've been part of meetings where local authorities and essential service providers have spoken out about the issues they face resulting from this switchover.

Some of them have been brutally scathing about Communications Providers like Virgin Media and BT.

Today's finding from OFCOM and the punishment handed down backs up those thoughts and comments.

Virgin Media fined £24m for leaving vulnerable customers 'at risk of harm'

Ofcom has fined Virgin Media after an investigation found it had left thousands of vulnerable telecare customers at risk.

It already exists, long since. But it's only available on SIP 'phones. Loop-disconnect signalling doesn't have the protocol for sending the data.

But on a SIP call the SBC can do what is known as a CNAM lookup when a call comes in, and fill in the initial INVITE with 15 characters of looked up information about the caller. There are various people/companies providing/selling CNAM lookup service.

If your 'phone company has switched over your landline to digital, this information (assuming that TPC's equipment is indeed doing the requisite CNAM lookups, which it possibly still isn't for residential subscribers) is now getting as far as a plastic box in your house and being thrown away there; because whilst it is now VoIP to that plastic box, there's no protocol for sending names from that plastic box over the RJ11/BT connectors and 2 wires to your 'phone. Caller ID is sent over that very last leg using DTMF.
